6 Claims. (Cl. -174) This invention relates to a collapsible childs bed.

An object of this invention is to provide a collapsible childs bed whichin the collapsed position thereof can receive the bedding.

Another object is to provide a childs bed which can readily be collapsedand brought into position of use and which is of small weight ascompared to its size so that one person can carry it without,inconvenience. As such a childs bed occupies but little space in thecollapsed position thereof, it may readily be put aside and be packedfor train, bus and car travels into a suitable cardboard containertogether with the bedding so that it is always ready for use.

A further object of the invention is to provide a collapsible childs bedwhich has a web preferably formed. into an endless belt and so united atits edges with an upper level frame and a lower frame. for the bedbottom that said web forms the side walls of the bed in the position ofuse thereof, while in the collapsed position of the bed it forms theside walls of a space which can receive the bedding.

The characterizing feature of the invention is that the two frames whichare both planar are so interconnected by means of hinged supports thatin the collapsed position of the bed the frames will be situated at adistance from each other which substantially corresponds to the heightof the bedding.

Further objects and features. of the invention will be described in thefollowing, reference being bad to the accompanying drawingsillustratingsome preferred embodiments of the bed according to thepresent invention. In the drawings:

Fig. 1 is a side View of the bed in its position of use.

Fig. 2 is a partial end view of the bed in its position of use.

Figs. 3 and 4 show in. detail how the web is attached to the bedaccording to two embodiments.

Figs. 5 to 7 show details of the web in the embodiments according toFigs. 3 and 4.

Fig. 8 shows a part of the bed in its collapsed position, as seen frombelow.

Fig. 9 is a side view of the bed in its collapsed position.

The childs bed comprises an upper frame 1 and a lower frame 2 on whichthe bed bottom is arranged, and four legs 3. The legs 3 are constitutedby two portions 4 and 5 which are hingedly interconnected by means ofhinges 6 or the like. At the joint a hasp 7 or the like is arranged forlocking the two portions 4 and 5 together in the position of use of thebed so that they form a rigid unit. At the underside of the upper frame1 which is wider and longer than the lower frame 2, the upper ends ofthe leg portions 4 are pivotally connected thereto by means of hinges 8or the like. At some distance from their free ends the leg portions 5are pivotally connected to the sides of the lower frame 2. For thispurpose the lower frame 2 is provided with pins, rivets 9 or the likewhich constitute the pivots for the leg portions 5.

The distance of the pivotal axis of the hinge 8 from the pivotal axis ofthe hinge 6 is as great as the distance from the pivotal axis of thehinge 6 to the rivet 9 so that when the bed is collapsed the frames 1and 2 will be moved together without displacement. The hinges 8 andrivets 9 are disposed a distance from the end walls of the bed such thatwhen the bed is collapsed the legs 3 will be situated substantiallyinside the surface of the upper frame 1.

To give the bed the desirable stability in the position of use thereofthe hinges 8 at the upper frame 1 are disposed somewhat closer to theend walls of the bed than are the rivets 9 at the lower frame 2, so thatthe legs 3 will converge somewhat towards the base. Furthermore, the legportions 5 are united at each end wall of the bed by means of plates 10of plywood or the like which in the position of use of the bed bearagainst the lower frame 2. One part of hinges 11 can be secured to theplates 10 if the latter have been given sufiicient strength, while theother parts of the hinges 11 are secured to the underside of the lowerframe 2, as will appear from Fig. 4, in which case the hinges 11 replacethe rivets 9.

A web 12. of plastic material or the like is attached to the frames 1and 2. This web which is preferably given the form of an endless belt isof such a width that in the position of use of the bed it will beexpanded between the frames. Due to the fact that the upper frame 1 isboth wider and longer than the lower frame 2 the web 12 will extendvertically in the position of use of the bed, provided that it has beensecured to the inside of the upper frame 1 and to the outside of thelower frame 2. It is advantageous to secure the web to the frames bymeans of strips. According to Fig. 3 the web 12 is folded about thestrip 13 which is screwed to the inside of the upper frame 1, andfoldedin the manner apparent from Fig. 5about the strip 14 which isscrewed to the upper side of the lower frame 2. In the embodimentaccording to Fig. 4 the upper frame 1 is provided on its inner side witha recess 15 in which a strip 16 is inserted and screwed fast. The web 12lies between the strip 16 and the recess is and is retained in that itis provided with a cord 17 in its margin, as will be apparent from Fig.6. In the lower margin of the web 12, see Fig. 7, there is also mounteda cord 18 which cooperates with the inner edge of a strip 19 screwedfast to the upper side of the lower frame 2.

For collapsing the bed the hasps 7 are first released from their lockingposition. Then the legs 3 are acted upon in such a way that the pivotalconnections at the hinges 6 are moved inwardly towards the middle of thebed. As a result of this the frames 1 and 2 are moved together so thatthey finally occupy the position shown in Figs. 8 and 9. The legportions 4 and S are thereby made parallel with the frames 1 and 2. Asthe legs 3 are mounted at the underside of the upper frame 1 the legportions 4 will be situated substantially between the two frames 1 and2, and a space is thus formed between the frames 1 and 2 and the foldedweb 12, which space is large enough to receive the bedding so that thebed can be ready for use in the collapsed position thereof.

The collapsible childs bed according to the present invention has, interalia, the following essential advantages: 1. it can receive beddings inits collapsed position.

2. It can be readily collapsed and brought into position of use.

3. It is of little weight as compared to its size and can be carried byone person without trouble.

4. it occupies in its collapsed position a very small space and it istherefore easy to put it aside and to pack it for train, bus and cartravels into a suitable cardboard container together with the bedding sothat it is always ready for use.

5. The web walls of the bed protect the child from draughts and directsun light when the bed is spaced outof-doors. By putting a frame offine-mesh netting over the top of the bed insects and the like will beprevented from disturbing and hurting the child.

6. The soft web walls of the bed which are of such a height that a smallchild cannot climb out of the bed cannot hurt the child as ribs or thelike do.

Of course, the invention is not limited to the embodiments describedabove and shown in the drawings, but can be varied in different wayswithin the scope of the appendant claims.

What I claim and desire to secure by Letters Patent is:

A collapsible childs bed comprising a level upper frame and a levellower frame, a bed bottom supported on said lower frame, a web in theform of an endless belt having its edges united with said upper andlower frames so as to form stretched side walls in the position of useof the bed to stabilize the bed and to form the side walls of a spacefor receiving the bedding in the collapsed position of the bed, hingedsupport means pivotally connected to said upper frame on the lowersurface thereof and to said lower frame and supporting said upper andlower frames in the position of use of the bed and so uniting said levelupper and lower frames that in the collapsed position of the bed saidframes will be spaced from one another to provide a space for receivingthe bedding.

2. A collapsible bed as claimed in claim 1 having hinge meansintermediate the pivotal connections of said support means to said twoframes, whereby the support means may be collapsed to lie parallel tothe planes of the said two frames and a space will be formed betweensaid two frames for receiving the bedding.
